11. Using a properly rated chain/cable, connect the spreader bar to the compressor lifting points.
12. Confirm that all lifting points are secured in accordance with relevant safety procedures and standards.
13. Connect an appropriate lifting device to the eyebolts provided on each side of the compressor.
14. Remove the four (4) compressor mounting fasteners and associated hardware from the base of the
compressor.
15. Lift the compressor approximately 100 mm (4”). Confirm that the compressor and spreader bar are
properly balanced between the lifting points and the lifting hoist.
16. Continue the removal of the compressor and lower to the desired location in order to remove the
chains/cables.
17. Using the blanking plates and bolts provided with the new compressor, seal the compressor and
charge to 15 psi with a nontoxic inert gas (e.g., nitrogen) for shipment (this will prevent moisture and
foreign material from entering the compressor).
3.3 Compressor Installation
NOTE
Blanking plates should not be removed from the new compressor until you are ready to place the new compressor in operation. New
compressors are pressurized with nitrogen to 15 psi. Pressure should be relieved through the Schrader valve, located next to the motor
cooling connection, prior to removing the blanking plates.
NOTE
Install new O-rings when attaching flanges to the compressor.
1. Relieve the inert gas pressure through the motor cooling exit port Schrader valve.
2. Remove the suction, discharge, and economizer (if applicable) blanking plates from the compressor.
3. Remove the motor cooling inlet adapter cap. Refer to Section 3.4 Compressor Replacement
Considerations for Motor Cooling Adapter on page 43.
4. Ensure that all connections have protective covers to prevent foreign object damage during
installation.
5. Attach the spreader bar to the two (2) lifting hooks (eye bolts) on the top of the compressor and
confirm that all lifting points are secured in accordance with relevant safety procedures and standards.
6. Position an appropriate lifting hoist/crane and connect to the spreader bar.
7. Confirm that the compressor and spreader bar are properly balanced between the lifting points and
the lifting hoist.
8. Slowly lower the compressor until it is positioned within approximately 5 mm (¼”) of the compressor
mounts.
9. Loosely install the rubber mounts and mounting fasteners to the base of the compressor.
10. Slowly release the load from the crane so that compressor weight is supported by the compressor
mounts.
11. Install and tighten the suction flange fasteners to 75 Nm (55 ft.lb.).
12. Install and tighten the discharge flange fasteners to 32 Nm (24 ft.lb.).
13. Install and tighten the economizer flange fasteners (if applicable) to 32 Nm (24 ft.lb.).
14. Torque the compressor mounting base fasteners to 14 Nm (10 ft.lb.).
